' I Application filed July 13, 1901. Serial No. 681180. (No model.)

To all whom it may concern: and a piston 16, preferably of asbestos. This Be it known that I, THEODORE E.

eye through which the spindle is passed, and a spring encircling, said spindle and bearing against said eye and forked end of the lever, substantially as set forth.

In testimony whereof I have signed this specification in the'presence of two subscribing witnesses.
